Abstract: 1,216,460. Protective arrangement; control systems for X-ray apparatus. LITTON INDUSTRIES Inc. 9 May, 1969 [16 July, 1968], No. 23861/69. Headings H2H and H2K. An X-ray equipment has means which continuously represent the instantaneous heat content of the X-ray tube 1. A transformer 30 has its primary winding 32 connected for energization in accordance with the voltage applied to the tube. A tapping 35 on the secondary winding of this transformer is coupled to and adjusted with the movable contact 29 of a rheostat 28 which, in controlling the heater current of the tube, controls the anode current. Thus the output from the winding 33 is dependent on the power supplied to the tube 1 and causes a motor 38 to drive a shaft 46 accordingly. A further motor 52 continuously drives a shaft 60 with the opposite direction of rotation, a slip clutch 50 being provided between the shafts. The shaft 46 carries a pointer 48 of a meter calibrated to indicate the number of heat units which can be generated in the X-ray tube before it is overloaded. When the pointer reaches the end of its travel it opens a switch (not shown) to de-energize a relay 78 which opens its contacts 82, 80 to terminate operation of the equipment. Alternatively, the pointer 48 may be replaced by the movable contact of a potentiometer controlling the energization of a separate member, Fig. 4 (not shown). -

[Also in Divisions B2 and B5] Belting is produced by continuously feeding a strip into contact with a travelling conveyer blanket at a predetermined point in its travel, maintaining a pool of liquid polyurethane on the blanket beneath the strip and in a position in advance of and adjacent to the line of contact between the strip and the conveyer blanket, maintaining a second pool of liquid polyurethane upon the upper surface of the strip near its line of contact with the travelling blanket thereby coating both sides of the strip as the strip is progressed by the conveyer blanket covering the strip as it is coated with an overlying blanket and then subjecting the polyurethane to curing heat while the strip is being advanced between the two blankets e.g. by passage over a heated table. As shown in Fig. 1, more than one strip may be passed continuously over the travelling conveyer blanket in spaced relationship and a pool of liquid polyurethane is maintained between the lowermost strip and the travelling blanket at a point in advance of the path of travel and adjacent to the line of contact between the bottom strip and the travelling blanket and between the or each additional intermediate strip in advance of the path of travel and adjacent to the line of contact of the intermediate strip or each intermediate strip and the underlying strip and in maintaining a pool of liquid polyurethane in advance of the path of travel of the superposed strip or strips and the subposed strip and covering the upper surface of each intermediate strip as it is coated with an overlying blanket, and effecting the curing of the polyurethane while the strips are advanced between the blankets. The blankets may be made of a non-adherent elastomeric material e.g. "Teflon" (Registered Trade Mark) or rubber-like elastomer which may be a silicone or sprayed with silicone. The pools of liquid polyurethane may be maintained in substantially constant volume. Gauging means for maintaining a constant predetermined thickness of the applied polyurethane coating may be provided. Liquid polyurethane may be supplied to the pools through transverse superposed members 29 which may be caused to reciprocate transversely relatively to the travelling strip or strips and blankets. The strip or strips may be of textile fabric e.g. of cotton woven from twisted or untwisted strands, or having warp strands of "Dacron" (Registered Trade Mark) and a filler of nylon. The underlying conveyer blanket may extend substantially beyond the overlying blanket or blankets to provide an open portion for the reception of the strip or strips. The strip to be coated may be drawn over a curved gauge member located behind the pool of liquid polyurethane so that the thickness of the coating is gauged as the strip is drawn below the curved gauge member.

Title: Dry lubricant
IPC: F16N15/00
Filed: 1956-08-03
Abstract: A composition suitable for lubricating highly-polished metal surfaces comprises graphite or molybdenum disulphide in finely-powdered form having adherently deposited thereon discrete particles of metal. Specific metals mentioned are nickel, tungsten and molybdenum.ALSO:A lubricating composition comprises graphite or molybdenum disulphide in finely powdered form having adherently deposited thereon discrete particles of metal.  Specific metals mentioned are nickel, tungsten and molybdenum.  The finely powdered graphite or molybdenum disulphide may be loosely pressed in thin form on a foil carrier, for example of polyvinyl chloride, and the carrier then passed slowly through a vacuum vaporizing chamber in which the exposed surface of the powder is locally coated with adherent discrete particles of metal, through the evaporation of the metal under vacuum and its condensation on the powder layer.  Thus, nickel vapour may be produced by heating nickel-plated tungsten wire.  After leaving the vacuum chamber, the metallized powder is removed from the carrier. In another vaporizing process, nickel carbonyl is passed over the finely powdered graphite or molybdenum disulphide heated to 200 DEG C.  The carbonyl decomposes and nickel is deposited on the powder in discontinuous form.

Title: Improved semiconductor devices and method of producing them
IPC: H01L29/00
Filed: 1966-05-31
Abstract: 1,131,151. Semi-conductor devices. GENERAL ELECTRIC CO. 31 May, 1966 [1 June, 1965], No. 24275/66. Heading H1K. In order to reduce the quantity of charge induced by the presence of a passivating layer on a surface of a semi-conductor body at which a PN junction emerges, the surface lies within 10 degrees of a (100) plane. The body may be grown epitaxially on a substrate or may be cut from a zone-melted grown rod which has either been grown directly with a [100] axis, or has been grown with the usual [111] axis and then cut to the desired orientation. Silicon or germanium devices may be made in this way, the former having SiO 2  passivating layers grown directly thereon, and the latter having such layers deposited, e.g. by sputtering or decomposition of suitable materials. The Specification includes descriptions of the manufacture of diffused planar diodes, transistors or M.O.S. field-effect transistors particularly for use in the P-channel enhancement mode, all using conventional masking, etching and diffusion techniques on a (100) plane. Boron and phosphorus are used as dopants, with evaporated aluminium electrodes. A metaloxide-semi-conductor voltage-variable capacitor which is described but not claimed, has an improved characteristic as a result of the relatively small number of surface energy states beneath the oxide layer. The invention is applicable to integrated circuits or to discrete devices formed in a single wafer and separated by cleaving prior to encapsulation.

Abstract: 738,450. Radio navigation. RADIO-INDUSTRIE. Sept. 3, 1953 [Sept. 12, 1952], No. 24419/53. Class 40 (7). A radio navigation system comprises a fixed radar equipment, a television transmitter fed with the radar display superimposed on a drawing or map, several television control receivers each having an adjustable marker generator the outputs of which are fed back to the transmitter, and, on a co-operating craft, a television receiver. At the fixed station the radar may give a P.P.I. display 2 which is viewed by the television camera 4 superimposed on a map 5 by means of half-spherical mirror 3. The camera output is fed to television transmitter 6 and also over line 7 to a number of control receivers 8, 9, 10 and 11 on which the' combined display is shown. Each of the control receivers is provided with an adjustable marker generator which its operator can align with any desired echo indication and the marker indications are fed back, by means not shown, so that they occur on the transmitted picture. The marker generator may be provided with two controls, one selecting the line in which the indication occurs and the other the position along the line (Fig. 4, not shown). There is also provided a switch whereby the marker indication on the control receiver and also that transmitted may be modulated in intensity at will at a frequency which is characteristic of the particular control receiver. When this modulation is brought into effect the modulating frequency concerned may also be transmitted to the craft by means of a multiplex radio link to assist the navigator to determine which echo signal on the televised picture represents his own craft. The multiplex radio link can also be used for speech in order to pass navigational instructions from the control receiver operator to the craft. If desired, an expanded trace and different map 5 may be used to increase the accuracy in a particular portion of the area normally covered. It is preferred to equip each craft with two television receivers.
